Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a V-type connector for a live-line work manipulator used when branching a high-voltage underline line from a high-voltage overhead distribution line, and its attachment device.

(Prior Art) Conventional V-type connectors have shapes as shown in FIGS. 11 and 12. In this V-shaped connector, a male type fastening metal fitting 1 and a female type fastening metal fitting 2 are brought together at a mating surface 8, and are biased by a torsion spring 3 so as to be able to open into a V shape.
, 2 and are tightenably connected with bolts 4.
The mating surface 8 is formed with uneven parts 1a and 2a consisting of a convex part 1a provided on the male type fastener 1 and a recessed part 2a provided on the female type fastener 2, and the center part is opened by the torsion spring 3. A draw line gripping portion 10 is formed at the position where is formed,
Furthermore, the six-car clamping hardware 1 has a distribution line gripping part 9 formed at a position farther from the opening center than the uneven parts la and 2a,
A bolt hole is formed in one of the holes 2, and a screw hole 1b is formed in the other.

In this example, the bolt 4 passes through the female type fastener 2 via the flat washer 5 and the spring washer 6, and is screwed into the screw hole 1b of the male type fastener 1, and then is inserted into the distribution line gripping part 9. The power distribution line 11 and the underline wire 12 held between the underline wire gripping parts 10 are held by tightening.

(Problem to be Solved by the Invention) However, in this high-voltage underlining work, two workers wear insulating protective equipment, and one worker attaches the underwire 12 to the V-type connector and connects all power distribution lines. However, since several workers had to tighten the bolts 4 with hand tools, the risk of electric shock and physical fatigue for each worker was severe. In addition, since the distance @Q between the uneven parts 1a and 2a of the V-type connector and the distribution line gripping part 9 was quite large, when opening the V-type connector and inserting the bare wire of the distribution line 11, the distribution line 11 was inserted too much and it was difficult to match. There was a risk that they would get caught on surface 8.

Therefore, it is an object of the present invention to provide a V-type connector and its attachment device that can prevent the distribution line from entering too much and can be attached by operating a manipulator.

(Means for Solving the Problems) In order to achieve this object, the V-type connector of the present invention includes a male type fastener having a convex portion formed on a mating surface, and a male type fastening metal fitting having a convex portion formed on the mating surface, and four parts receiving the convex portion on the mating surface. The formed female type fastening hardware is biased by a torsion spring so as to be able to open in a V shape, and a draw line gripping portion is formed at the opening center of the mating surface of both the fastening hardware, A distribution line gripping portion is formed at a position away from the center of the opening, and the uneven portion is formed between the distribution line gripping portion and the pull-down wire gripping portion to extend the diameter of the bare wire of the distribution line. The two fasteners are formed at a position less than half of the dimensions of ■For a manipulator for live wire work, characterized in that the object is formed with a protrusion for easy holding of the clamping hardware.
It is a type connector.

Further, the V-type connector attachment device of the present invention is a V-type connector attachment device for attaching a V-type connector for a live-line work manipulator to a power distribution line, and includes a box socket that holds the bolt head of the V-type connector.

The V-type connector attachment device is characterized by comprising a first driving means for driving the box socket, and a second driving means for moving the pull-out plate and the holding part in conjunction with the first driving means. .

(Operations and Effects of the Invention) According to the present invention, in the V-type connector, a protrusion is formed on the fastener provided with the screw hole for the bolt to easily hold the fastener, Since the distance Q between the part and the uneven part is less than half the diameter of the bare wire of the distribution line, the V-type connector can be easily held by the bolt head and the protruding part, and the mating surface can be easily held. Even if an attempt is made to pinch the wire, the wire moves to the correct position and is gripped by the gripping portion, so there is no chance of the power distribution line being pinched by anything other than the distribution wire gripping portion.

Since this is a V-type connector, it can be easily held in the mounting device and tightened, and since a pull-out plate is provided, the V-shaped connector can be easily removed from the mounting device after tightening. Underlined branching operations can be easily performed.

(Example) The present invention will be described below with reference to the accompanying drawings.

A fastener 5 in which a screw hole 1b for a bolt 4 is formed. Here, a protrusion 7 is formed in the screw hole 1b of the male fastener 1 to facilitate holding. Although this protrusion 7 is not limited to the position of this screw hole 1b, it is provided here in this example because it is located in a straight line with the bolt 4 and it is easy to apply force, and this shape is also Any shape that makes it easy to hold the V-shaped connector may be used, but to simplify the tool, it is formed integrally with the fastening hardware 1, for example, in the shape of a hexagonal nut, which is compatible with commercially available tools. Furthermore, the uneven portion 1a,
The dimension Q from 2a to the distribution line gripping part 9 is set to be less than half the diameter of the bare wire of the distribution line 11. By doing this, even if the V-shaped connector opens and a gap is created below the distribution line gripping part 9 and the bare wire of the distribution line 11 is pinched, the distribution line 11 will be removed from the distribution line gripping part during the tightening process. 9 and fits, so grip the distribution line 11 completely in the predetermined position.

FIG. 3 shows a state in which the ■-shaped connector is attached to the distribution line 11, and the down line 12 is also sandwiched between the V-shaped connectors and branched.

Moreover, FIGS. 4 to 9 are views showing an embodiment of the invention of a mounting device for mounting this V-type connector. In the figure, 26 is a main body frame attached to a manipulator attached to an aerial work vehicle.
A drive shaft 21 and a second drive shaft 22, which is a second drive means, are provided. Each drive shaft 21, 22 has a hexagonal head protruding within a cylindrical drive connection part 23, 24 fixed to the main body frame 26, and is attached to a manipulator (not shown) to transmit rotational drive. Also, the surface drive connection part 23.24
A connecting fixing pin 25 provided on the main body frame 26 between
It is removably fixed to a manipulator (not shown).

On the other hand, the first drive shaft 21 is set to be perpendicular to the tightening shaft 28 via the bevel gear 27, and the tightening shaft 28 is provided as a horizontal shaft above the main body frame 26, and a box socket 29 is attached to the tip of the first drive shaft 21. is attached removably. This box socket 29 has a hexagonal hole formed therein so as to be able to hold the head of the bolt 4 of the V-shaped connector.

Box sockets 29 of various sizes are prepared for bolts 4 of different sizes depending on the type of V-type connector. As shown in FIG. 4, a pull-out plate 33, which is provided opposite to the box socket 29 and can be freely moved toward and away from the box socket 29, is bent in a straight line, and an opening 33a without a rim is provided above. The pull-out plate 33 is integrated with a rack 30 parallel to the tightening shaft 28 and a slide shaft 32, and the rack 30 is connected to a spur gear 3 provided at the upper end of the second drive shaft 22.
It meshes with 1. A slide hardware 36 is provided on the rack 30 and the slide shaft 32 so as to mesh with the rack 30 and slide freely toward and away from the pull-out plate 33.The slide hardware 36 has a V-shaped connector on the opposite side of the pull-out plate 33. In order to reliably hold the protrusion 7 , a holding part 38 having, for example, a part of a hexagonal shape that matches the hexagonal shape of the protrusion 7 is provided coaxially with the tightening shaft 28 . Further, the slide hardware 36 is provided with a wire guide 37 that guides the power distribution line 11 to the power distribution line grip portion 9 when the ■-shaped connector is open. The push button 35 provided on the slide hardware 36 is pressed down to release the slide hardware 36.
The interlock between the rack 3o and the rack 3o is cut off, and the rack 3o is movable on the slide shaft 32. Therefore, when the push button 35 is not pressed, the second drive means 22 receives the drive from the manipulator so that the pull-out plate 33 and the holding part 38 operate in conjunction with the first drive means 21.

FIG. 10 is a diagram showing another embodiment of the invention of a mounting device for mounting a V-type connector. This is completely the same as the mount shown in FIG. 4, except that a draw-line gripping device is added in a direction perpendicular to the main body frame 26. This pull-down wire gripping device is provided with arm plates 39 extending in a direction parallel to the power distribution line 11 on both sides of the main body frame 26.
A vertical plate 40 extending in the extending direction is attached to the upper surface of the distal end position, and a clamping plate 41 is attached to face this vertical plate 40 so as to be pressed downwardly at two places by the force of a spring 42. Sandwiching plate 4
1 and the vertical plate 40, each having a recess 4 on the facing surface.
3,44 are provided.

Both recesses 43 and 44 form a portion for holding the draw line 12. Furthermore, an opening/closing knob 45 for opening and closing the clamping plate 41 is provided above the spring 42. When the opening/closing knob 45 is operated and opened, the upper ends of the vertical plate 40 and the clamping plate 41 open, and both recesses 43,
44 is separated so that the covered portion of the draw wire 12 can be received therein.

When operated in the closed position, the draw wire 12 can be held between the two recesses 43 and 44.

The installation work of the V-type connector installation device configured as above will be explained.

By loosening the bolt 4 of the V-shaped connector shown in FIGS. 1 and 2, the male clamping hardware 1 and the female clamping hardware 2 are expanded by the force of the torsion spring 3, and the draw-down line gripping portion 10 is slightly opened. The loop of the torsion spring 3 forms the center of this opening, and the uneven parts 1a and 2a also form the distribution line grip part 9.
is also open. Connect this open V-shaped connector to the fourth
Set it in the V-type connector shown in the figure. Pull-out plate 33
Insert the head of the bolt 4 into the opening 33a as shown in FIG. Move it to the left so that the head of the bolt 4 enters the box socket 29, press the push button 35 so that the protruding part 7 enters the holding part 38, and move the sliding metal fitting 36 to stably hold the V-shaped connector. At this time, the protruding part 7 and the holding part 38 are engaged to support the V-shaped connector so that it does not rotate. Therefore, the pull-out plate 33 and the sliding hardware 36 have moved to the left from the position shown in FIG.

The V-type connector attachment device with the V-type connector opened and set is securely attached to a manipulator (not shown in FIG. 1) using a connecting fixing pin 25, and brought close to the distribution line 11. Distribution line 1
Wire guide 3 is placed at the position of the bare wire 11a from which the covering of No. 1 has been peeled off.
7 so that the bare wire 11a of the distribution line 11 enters the distribution line grip part 9. At this time, the uneven portion 1a,
Since the dimension Q up to 2a is less than half the diameter of the bare wire 11a, even if the distribution line 11 enters until it hits the uneven parts 1a and 2a, it will not be pushed back to the distribution line grip part 9 during the primary tightening operation. It will be done.

Incidentally, by pinching the tip of the draw-down wire 12 with the tip of the V-shaped connector, the draw-down wire gripping portion 10 is forcibly inserted into the open position, the pinching force is removed, and the clamping is completed in advance.

After confirming that the bare wire 11a of the power distribution line 11 has entered the power distribution line gripping part 9, the manipulator is operated to drive the first drive shaft 21 and tighten the bolt 4. Since the V-type connector is closing, the holding part 38 is sent in that amount. In this way, the V-type connector is tightened. When the distribution line 11 and the pull-down line 12 have been tightened and gripped, the first drive shaft 21
The drive of the pull-out plate 3 is stopped, and the second drive shaft 22 is driven.
The head of the bolt 4 can be easily pulled out from the box socket 29. When the push button 35 is pressed, the latch is released and the sliding hardware can be moved through the rack, but when the rack moves to the left in Figure 5, the latch is re-engaged and the rack and sliding hardware move together as one. do. In this case, if the rack is moved to the right in FIG. 5, it will become as shown in FIG. In this situation, operate the manipulator to move the V-type connector attachment device downward, and as shown in Figure 3, separate the V-type connector attached to the distribution line 11 from the attachment device to complete the downline branching work. .

In addition, Fig. 10 shows a drawing line gripping device added.
In the case shown in FIG. 4, when the V-type connector is set at the pull-out plate 33,
It is loose and can be opened. Therefore, although the hole in the draw-down line gripping part 10 is also held down by the torsion spring 3, it is slightly closed, and in this state, the bare wire part of the draw-down line 12 is only inserted, but it is not inserted. Since the part was long and heavy, the puller easily fell from the drawer wire grip part 10. Therefore, when setting the V-type connector on the pull-out plate 33, align the covering portion of the draw-down wire 12 extending from the V-type connector with the positions of both recesses 43 and 44, and sandwich it between the vertical plate 40 and the clamping plate 41. Hold. Therefore, by carrying out the above-mentioned work in this state, the bare wire part of the drawer wire 12 will not fall out of the V-shaped connector during the work and the drawer wire branching work will be completed reliably. Note that the vertical plates 40 and clamping plates 41 for gripping the covered wire portion are provided on both sides of the main body frame 26 as pull-down edge gripping devices, but this is because the draw-down wire 12 can be handled for wiring on either side. be.

Therefore, by simply operating the manipulator attached to the aerial work vehicle, workers can safely perform underline branching work during live wire work, which was previously dangerous and tiring.

It can be done reliably and quickly.
